SOLAR & ATRILAZE Atrial Fibrillation Trial (SAAF-T)

The recruitment status of this study is unknown. The completion date has passed and the status has not been verified in more than two years.
Verified August 2008 by EndoPhotonix, Inc..
Recruitment status was:  Not yet recruiting

The purpose of study is to conduct a pivotal evaluation of the EndoPhotonix™ SOLAR™ System and ATRILAZE™ System in order to obtain a labeling claim on the devices for the treatment of atrial fibrillation.

The study will test the safety and effectiveness of the EndoPhotonix™ Laser Ablation Systems to photocoagulate cardiac tissue during cardiac surgery, to create electrical isolation of the pulmonary veins and create other electrical isolation lesions in order to treat atrial fibrillation. The surgical procedure will be conducted during concomitant mitral valve repair or replacement surgery or in combination with other cardiac surgery including aortic valve surgery, tricuspid valve surgery, or coronary artery bypass surgery.

Primary Outcome Measures:
  • Freedom from atrial fibrillation by 24-hour 3-lead Holter Monitor at the 180 day evaluation. On or Off Class 1 and III anti-arrhythmic medication [ Time Frame: 180 days ]
  • Acute SAE: Death, mediastinitis, myocardial infarction, stroke, transient ischemic attack (TIA), pulmonary embolism, peripheral arterial embolism, esophageal injury, pulmonary vein stenosis; phrenic nerve damage [ Time Frame: 0 through 30 days or length of stay ]

Secondary Outcome Measures:
  • SAE: Death, mediastinitis, myocardial infarction, stroke, transient ischemic attack (TIA), pulmonary embolism, peripheral arterial embolism, esophageal injury, pulmonary vein stenosis; phrenic nerve damage [ Time Frame: 180 days ]
  • Determine binary freedom from AF, independent of anti-arrhythmic status as documented by 24 hour 3-Lead Holter Monitor. Reduction of AF burden with assumption of 100% initial burden. To establish improvement in Quality of Life. [ Time Frame: 180 days ]

Estimated Enrollment: 90
Study Start Date: December 2008
Estimated Study Completion Date: June 2012
Estimated Primary Completion Date: January 2012 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Persistent AF
Treatment arm to be compared with historical control.
Device: Laser MAZE by Ablation of Cardiac Tissue
The protocol calls for the creation of the pulmonary vein isolation lesion through the use of the SOLAR™. The additional lesions are to be created using the ATRILAZE™. At surgeon discretion, the ganglia may be ablated and left and right atrial appendages may be removed.
Other Names:
  • Maze
  • Maze procedure

Detailed Description:
The study objective is to generate Level II controlled data to support the expansion of indications for the SOLAR™ System based on 0-30 day data; as well as to support the expansion of indications for the SOLAR™ System and ATRILAZE™ System for the treatment of atrial fibrillation based on 180 days data. The data will be evaluated by comparing post-operative data to the historical control data. The subjects in the study cohort will receive laser ablation therapy using the investigational device during a concomitant surgical procedure.

Ages Eligible for Study:   18 Years and older   (Adult, Senior)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

Inclusion Criteria:

    • Mitral valve repair or replacement
    • Aortic valve repair or replacement
    • Tricuspid valve repair or replacement
    • Atrial septal defect (ASD) repair
    • Patent foramen ovale (PFO) closure
    • Coronary artery bypass procedure
  • Be able to take anticoagulation therapy (Warfarin / Coumadin®)
  • Be able to fulfill study requirements
  • Willing and able to comply with the requirements of the protocol including follow-up requirements
  • Willing and able to sign a study specific informed consent

Exclusion Criteria:

  • Life expectancy < 1 year
  • NYHA class = IV
  • Left ventricular ejection fraction (LVEF) measurement <30%
  • Left atrial diameter > 7.5 cm
  • Wolff-Parkinson-White (WPW) Syndrome
  • Pregnancy or desire to be pregnant within 1 year of the study treatment
  • Myocardial infarction within the previous 6 weeks
  • Presence of a previously implanted device (valve, CS leads, or ICD)
  • Known allergy, contraindication, or inability to comply with warfarin (Coumadin®) or heparin therapy
  • Known allergy or contraindication to complying with anti-arrhythmic (Class IA, IC, III) therapy
  • Previous thoracic procedure resulting in sternal opening and/or pericardial opening (e.g., CABG, valve replacement or repair)
  • Current diagnosis of active endocarditis, local or systemic infection
  • Renal failure requiring dialysis or hepatic failure
  • Emergent cardiac surgery (cardiogenic shock)
  • Preoperative need for intra-aortic balloon pump, IV inotropes or vasoactive agents
